Abstract (en)
This application provides a precoding method and a communication apparatus in a satellite communication system. Considering that a satellite communication channel is mainly affected by a large-scale channel, and the large-scale channel is mainly determined by a free path loss, a network device performs precoding based on the large-scale channel by using an open-loop or closed-loop precoding technology. Therefore, unnecessary channel measurement of a terminal device can be reduced, a good performance gain can be obtained, and precoding performance of the satellite communication system can be improved.
